Experienced gardeners share their insights in answering this question :
First thing i would do,check the water level in the battery,don’t have to on a ” Maintenance Free ” battery. Remove both cables,from the battery,clean the cables with a wire brush,especial made for this.There can be a small film of acid oxidation deposit forming,that get into the cable clamps and the battery posts.This causes the cables not to make good contact with the posts. There is something else you can do and that,is use a portable battery charger. Try to charge up the battery with that,this would eliminate the tractor’s charging system causing the problem. If this battery won’t take a charge or hold a charge,the battery is bad.Hope this helps.Sincerely,Brad Locke DTD 12/04/15

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If your lawn mower battery won`t hold a charge, verify connections are clean and tight first, then connect it to the charger. If it isn`t fully charged within 8 hours, your battery is dead and you`ll need to replace it. If your lawn mower battery does charge fully, the charge should not drain if it is not in use.
A riding lawn mower with an especially small engine may have a 6-volt battery. The lawn mower`s alternator keeps its battery charged. A few hours of mowing recharges it the same way hours of highway driving can keep your car battery mostly charged. You might not mow the lawn in winter.
Alternator Test on Your Small Engine

For the easiest alternator test, simply turn on the headlights to your lawn mower or outdoor power equipment. Then, turn off the engine. If the lights dim, the alternator works. If not, it doesn`t.

Riding lawn mowers use a battery to turn over the engine and power extra components such as headlights and electric clutches. Your mower also has its own charging system that recharges the battery when the engine is running.
You can also attempt to recover the battery by overcharging the fully charged battery using a low amp trickle charger. Charge the battery for 24 hours using a regulated current of 200mA (milliAmps). This will boost the battery`s terminal voltage to 2.50-2.66 volts per cell and raise the battery`s internal temperature.
One issue is loose cables where they connect to the battery posts. A loose connection makes a battery work harder, thereby draining it of power more quickly. Cleaning the posts and tightening the connections should renew the battery`s ability to hold a charge. A larger problem is a cracked battery case.
The symptoms of your lawn mower battery going bad include the engine not starting, the mower producing clicking noises and a rotten egg smell, the battery losing charge faster than normal, the mower refusing to cut grass, and poor fluid levels.
A new lawn battery should last between three and five years. In order to achieve that, however, it`s important to perform regular maintenance. Here are a few tips to help you get the longest life possible out of your battery.
If you are using a 10-amp charger, your mower`s battery should charge in approximately one hour. Of course, connecting the battery to a lawn mower battery charger that has fewer amps may extend charging time.
Most riding mowers take a 12 volt battery, although some smaller mowers rely on a 6 volt battery. If you`re unsure what type of battery your mower requires, you can check the voltage of your old battery, or look up the information in your owner`s manual or on the manufacturer`s website.
The factors that keep draining your lawn mower battery include damaged, loose, or corroded cables, an electronic drain, or cables that are attached loosely. Sometimes, it is as simple as the battery needing some maintenance. Other plausible reasons are faulty alternators, voltage regulators, and battery chargers.
Riding mowers use a 12 volt electrical system. The battery should have 12.6 volts when fully charged and in good condition. If you are experiencing a problem with your product, find a solution by using our support assistant.
Luckily, you can charge your battery without removing it from your mower—so, go ahead and leave it in place. Connect the positive clamp then the negative clamp to the battery.
Riding lawn mowers are powered by an engine, and every engine has alternators to help it in moving the lawn mower. The alternator`s job is to maintain the lawn mower battery at a constant level.
A lawn mower will not run with a dead battery. The battery is necessary to provide the power needed to start the engine and keep it running. Without the battery, the engine will not be able to start and the mower will not be able to function.
Most manufacturers recommend charging your lawn mower battery at least once a month during the summer months and at least once a week during the winter months.

Battery?, wiring?? Had a recent problem with blades not engaging. I have had also had a slightly older issue of battery not holding charge so i have to boost or jump start mower. I went out and bought brand new battery and after one usage it would not hold charge and blades will still not engage. Would the issue related to the battery effect the engagement of the blades???
ANSWER : If your Alternator didn’t charging the battery, even though you brand new battery will not last. So there is two possible cause, 1) Your Alternator is not functioning. 2) there is a wiring problem that causing your battery to discharge easily, but you check it after you switch off the key remove the battery negative terminal then touch it back to batt term. and see if there is little blue spark, if does your wiring system got problem. If not, so your Alternator do not charge the battery.

Why do i keep fouling da spark plug? i remove it clean it and it runs about 15 or 20 seconds and stallsand plug is bkack and fouled AGAIN
ANSWER : Sounds like you are burning a lot of oil or you used two cycle fuel instead of regular gasoline. If you used the wrong fuel, drain tank and carburetor and it will clear up pretty quick. If you used the right fuel, did you overfill the oil? If oil level is where it should be, and the right fuel was used, then the alternatives from there fall into the not so good catagory, and they all involve at least some amount of engine disassembly.Good luck.

Battery goes dead over night – Toro 42'' Zero Turn Lawn Mower Trailer Package Deal ()
ANSWER : First thing to do is find out if it’s the battery or the mower. Disconnect the battery and leave it overnight. If it’s dead in the morning, you need a new battery. If not, you either have a charging problem (not likely if the battery isn’t dead after using the mower) or you have a current drain.

2010 model 20 hp Briggs motor. Fuel going through fuel line, but not going into carberator. Motor runs good for about 15 min, but after heating up this fuel problem starts. After cooling down for an hour it will run again for about 15 min.\r\nThanks for any advice
Tom in AR
ANSWER : Two things:
1 Is fuel coming out of the fuel line. Older mowers have old fuel lines and they tend to get weak and collapse went they warm up with engine heat. Replace the old fuel line.
2 deposits in the carb. take off the air cleaner, start it up and spray a good carb cleaner in the carb until the engine dies. Put some ‘seafoam’ in the gas and a little in the oil and put the air cleaner back on and start the mower and mow on FULL THROTTLE. this should claen out the carb. Yes the mower will run rough for awhile.

these two cheap fixes will solve 85 % of carb problems. GOOD LUCK
